用参数 数组方法编写代码,学员属性有姓名,学号,年龄,成绩,方法有添加学员信息,根据学员学号查找学员信息,展示所有学员信息(已录入的),根据查找学员姓名修改学员分数,对学员的成绩进行成绩的排序(排序后,)java

以下是使用参数数组方法编写的代码：

public class StudentManagement {
    private String[] names;
    private String[] ids;
    private int[] ages;
    private int[] scores;
    private int count;

    public StudentManagement(int capacity) {
        names = new String[capacity];
        ids = new String[capacity];
        ages = new int[capacity];
        scores = new int[capacity];
        count = 0;
    }

    public void addStudent(String name, String id, int age, int score) {
        names[count] = name;
        ids[count] = id;
        ages[count] = age;
        scores[count] = score;
        count++;
    }

    public void findStudentById(String id) {
        for (int i = 0; i < count; i++) {
            if (ids[i].equals(id)) {
                System.out.println("姓名：" + names[i] + "，学号：" + ids[i] + "，年龄：" + ages[i] + "，成绩：" + scores[i]);
                return;
            }
        }
        System.out.println("找不到该学号的学生！");
    }

    public void showAllStudents() {
        System.out.println("已录入的学生信息：");
        for (int i = 0; i < count; i++) {
            System.out.println("姓名：" + names[i] + "，学号：" + ids[i] + "，年龄：" + ages[i] + "，成绩：" + scores[i]);
        }
    }

    public void updateScoreByName(String name, int score) {
        for (int i = 0; i < count; i++) {
            if (names[i].equals(name)) {
                scores[i] = score;
                System.out.println("已将学生 " + name + " 的成绩修改为 " + score + " 分！");
                return;
            }
        }
        System.out.println("找不到该姓名的学生！");
    }

    public void sortStudentsByScore() {
        for (int i = 0; i < count - 1; i++) {
            for (int j = 0; j < count - i - 1; j++) {
                if (scores[j] < scores[j + 1]) {
                    int tempScore = scores[j];
                    scores[j] = scores[j + 1];
                    scores[j + 1] = tempScore;
                    String tempName = names[j];
                    names[j] = names[j + 1];
                    names[j + 1] = tempName;
                    String tempId = ids[j];
                    ids[j] = ids[j + 1];
                    ids[j + 1] = tempId;
                    int tempAge = ages[j];
                    ages[j] = ages[j + 1];
                    ages[j + 1] = tempAge;
                }
            }
        }
        System.out.println("按照成绩排序后的学生信息：");
        for (int i = 0; i < count; i++) {
            System.out.println("姓名：" + names[i] + "，学号：" + ids[i] + "，年龄：" + ages[i] + "，成绩：" + scores[i]);
        }
    }
}

其中，我们使用了一个名为 `count` 的变量来记录已经添加的学生数量，以便在查找、展示、修改和排序时不会遍历整个数组。在 `sortStudentsByScore()` 方法中，我们使用了冒泡排序的算法来按照成绩对学生进行排序。你可以在主函数中创建一个 `StudentManagement` 对象，然后调用其方法来完成对学生的管理。
